Miele Coffee System Not Brewing
Coffee System Not Brewing is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Mineral scale buildup
Hard water affects the brew group and internal lines the same way it affects any espresso machine.
A worn brew group or pump
The mechanical heart of the machine wears with regular use.
A clogged grinder or water line
Restricts flow and can affect both brewing and grinding performance.
Local conditions that matter here
Hetch Hetchy water arrives at 1 to 3 grains per gallon, among the softest supplies in the country, so scale is rarely the answer in this city. Soft, low-alkalinity water lays down no protective film and slowly strips the one that is there, which is why failures here show up as pitting and weeping joints on copper fill lines rather than as a furred-up valve.

In and around San Francisco
San Francisco — Two in five homes here predate 1940 and a great many predate built-in refrigeration entirely, so the constraint is usually the room rather than the appliance -- short cabinet depth, ventilation into a lightwell, and service sized for another century. We also cover Ross, San Anselmo, San Rafael across San Francisco.
